The end of the wait for RIM's eagerly awaited BlackBerry PlayBook tablet is coming April 19 but could the tablet have arrived sooner? Perhaps. If so, you might blame Apple, which created a touchscreen glass shortage with its iPad 2 manufacturing.

According to Digitimes, "Sources from touch screen panel makers also pointed out that PlayBook shipments were postponed for about a month from the original schedule due to a delay in software testing as well as shortage of touch panels because Apple already booked up most of the available capacity."
